Summer - The HTML5 Library for Java and Scala

Summer - The HTML5 Library for Java and Scala

Summer is the next generation presentation layer library for Spring MVC. It provides the world's best HTML5 template engine and takes advantage of many Spring features like MVC annotations and data binding, content negotiation, REST support, conversion and various others. In addition it supports a number of Java EE 6 specifications including Servlet 3.0, JPA 2.0, Bean Validation and EL 2.2.

Summer enables the creation of true web modules that package every required static resource. It also makes AJAX really simple by providing partial page rendering capabilities. Support for HTML5 WebSockets is available through the popular Atmosphere framework.

Quickstart

You can create and run a blank Summer project by using the following commands:

mvn archetype:generate -DarchetypeCatalog=http://www.asual.com/maven/content/groups/public/archetype-catalog.xml
mvn eclipse:eclipse -DdownloadSources=true
mvn jetty:run

Specify the dependencies manually

summer's Issues

Error in opening Zip file crashes server

Web app using summer experiences the following behaviour deployed using Tomcat 6.0.24 on Ubuntu server: some time after deployment there is an error in opening some part of the application dependencies archive. As a result the entire web application crashes and only a restart of the container fix this. Looks as if there is a jar file being changed and reloading it fails, causing a restart of the server (fails too). Here is a related issue: http://forums.devshed.com/java-help-9/error-in-opening-zip-file-59448.html

incorrect iteration over maps

When I try to iterate over a Map<String,Map<String, Object> with the followin code, a NPE is always thrown, because the 'item' var is always an empty string(most probably null before some casting occurs) in the second 'data-repeat' attribute statement.

 <ul data-repeat="${listAnnComparator.sortList(annotations.keySet())}" data-var="item">

   <li data-rendered="${item != 'sections' && item != 'debugAnnotations'}">
    <span>${item}</span>
    <ul data-repeat="${listAnnComparator.sortList(annotations.get(item).keySet())}" data-var="item2" data-rendered="${annotations.hasNext(item)}">
